Introduction

Getting started

  integer( i4b ) :: ierr
  CALL GMSH_INIT
  ierr = gmsh%initialize()
  ierr = gmsh%open(fileName="t1.msh" )
  ierr = gmsh%write(fileName="t2.msh")
  ierr = gmsh%finalize()
  ierr = gmsh%clear()
  CALL GMSH_FINAL

Methods

Initialize

This function will start the Gmsh engine, and it allocates the pointer fields.

FUNCTION Initialize( obj ) RESULT( ans )
  CLASS( Gmsh_ ), INTENT( INOUT ) :: obj
  INTEGER( I4B ) :: ans

Finalize

This function will stop the Gmsh engine

FUNCTION finalize( obj ) RESULT( ans )
  CLASS( Gmsh_  ), INTENT( INOUT ) :: obj
  INTEGER( I4B ) :: ans

Final

This function will stop the Gmsh engine

SUBROUTINE GMSH_FINAL
END SUBROUTINE GMSH_FINAL

Open

Open a file. Equivalent to the File->Open menu in the Gmsh app. Handling of the file depends on its extension and/or its contents: opening a file with model data will create a new model.

FUNCTION Open( obj, fileName ) RESULT( ans )
  CLASS( Gmsh_ ), INTENT( INOUT ) :: obj
  CHARACTER( LEN = * ), INTENT( IN ) :: fileName
  INTEGER( I4B ) :: ans
END FUNCTION Open

Merge

Merge a file. Equivalent to the File->Merge menu in the Gmsh app. Handling of the file depends on its extension and/or its contents. Merging a file with model data will add the data to the current model.

FUNCTION Merge( obj, fileName ) RESULT( ans )
  CLASS( Gmsh_ ), INTENT( INOUT ) :: obj
  CHARACTER( LEN = * ), INTENT( IN ) :: fileName
  INTEGER( I4B ) :: ans
END FUNCTION Merge

Write

Write a file. The export format is determined by the file extension.

FUNCTION Write( obj, fileName ) RESULT( ans )
  CLASS( Gmsh_ ), INTENT( INOUT ) :: obj
  CHARACTER( LEN = * ), INTENT( IN ) :: fileName
  INTEGER( I4B ) :: ans
END FUNCTION Write

Clear

Clear all loaded models and post-processing data, and add a new empty model.

FUNCTION Clear( obj ) RESULT( ans )
  CLASS( Gmsh_ ), INTENT( INOUT ) :: obj
  INTEGER( I4B ) :: ans
END FUNCTION Clear
